Check whether the announcement actually names your symptom
A patch note can narrow a diagnosis, but it is not a general guarantee for every crash, camera hang, or missing follower. The August 26 announcement names a set of fixes; several can be matched to a concrete symptom. It does not show separate Windows, Mac, PlayStation, Xbox, and Switch build numbers in the same notice.
| Observed symptom | Named in 1.5.26? | First safe check | Limit |
|---|---|---|---|
| Player 2 appears outside the dungeon room | Yes: second player occasionally spawned out of bounds entering dungeon nodes | Check your platform's installed update history against the 1.5.26 announcement | The note does not promise every co-op OOB case is fixed |
| Camera stays stuck after removing Player 2 | Yes: co-op camera issue when removing second player | Reproduce the same sequence after updating, if safe | No universal camera-recovery procedure is given |
| macOS expanded base disappears after reload | Yes: some Mac users' expanded base deleted on reload | Check the exact platform/build and preserve the save before further experiments | The note says some users; it is not a save restore guide |
| Different issue, or no matching patch record | Not established by this list | Use the in-game bug report icon and document exact reproduction steps | Do not claim 1.5.26 resolves an unlisted issue |

Report the smallest reproducible case
Massive Monster's patch note asks for the issue and steps that reproduce it, and points to the in-game bug-report path through the pause menu. Keep a copy of the exact build/platform and distinguish what you saw from what you expected. Do not post account credentials or private save data in a public discussion.
- Record platform/storefront and the version shown by that platform; do not copy another platform's build number.
- Name the affected save context and location only as needed. Do not include a full save file in a public post.
- Write numbered steps from a fresh load or reproducible point, then the expected and observed result.
- State whether the issue matches a named 1.5.26 note, without claiming that the patch fixed it unless you confirmed the result yourself.
- Use the in-game pause-menu bug icon as the developer requests; Steam Discussions are an alternative venue mentioned by the developer, but posts are user-generated.
- Review any evidence for usernames, email addresses, server identifiers, private paths, or personal information before attaching it.

Format the report locally
The browser builder below creates text from fields you type. It does not read the game, access a save or log, or send the report. Copying it is your choice; use the official in-game path for an actual submission.

Before you play
- Compare the exact symptom with the named 1.5.26 notes before trying workarounds.
- Verify your own storefront/platform update state; do not transpose a PC announcement to a console build.
- Preserve saves before experimenting with an issue described as reload-related.
- Use the pause-menu bug report icon and provide exact reproduction steps.
- The browser builder does not read files or submit a ticket; remove private details before sharing.
Frequently asked questions
Does Patch 1.5.26 fix every stuck camera or out-of-bounds issue?
No. It names specific occasional symptoms, including a co-op camera issue when removing Player 2 and the second player spawning out of bounds on dungeon-node entry. Other symptoms are not covered by that wording.
Did the Mac base deletion issue affect every save?
The note says some Mac users' expanded bases were deleted on reload. It is not a general statement about all Mac saves and does not provide a restoration procedure.
Where does the developer ask me to report a bug?
The patch note says to report in-game from the pause menu using the bug icon, with details and steps to reproduce; it also points to Steam Discussions if needed.
Can GamerWin submit or attach my save/log?
No. The builder formats only text entered in the page; it reads and uploads no files and submits no ticket.
